Abstract: A new algorithm was proposed to partition triangular meshes into quadrangular segmentation automatically. By this approach, first the triangular meshes are segmented according to the normal vectors of the triangle. Then, the resultant segmentations are partitioned into regions with three or more sides based on Euclidean distance. After the segmentation of multisided region into subregions with three or four sides, the final quadrangular segmentations are obtained by adjusting the triangular regions according to their topology sequences. The algorithm is able to accommodate the geometric characteristics of the model to partition triangular meshes into quadrangular regions with appropriate sizes. The final segmentation matches the features of the model well.

Key words: computer application, quadrangular region segmentation, heuristic, triangle meshes
